Cold and wet weather are expected in large parts of South Africa from today (Thursday) into the weekend, May 20 to 22.

The South African Weather Service released a statement saying a steep upper-air trough system will develop into a cut-off low pressure system over the north-western interior of the country by Friday, May 20.

Widespread rainfall can be expected over the southern and central parts of the country from Thursday onwards, with light snowfalls likely over the mountainous, high-lying areas of the Western and Eastern Cape, spreading to the Lesotho Drakensberg regions by the weekend, where heavier falls are anticipated.

Light snowfalls can also be expected over the high-lying ground of south-eastern and eastern Free State.

Some 24-hour rainfall accumulations of 25 to 35mm can also be expected over the drought-stricken parts of the Eastern Cape.

Moreover, there is also the possibility of isolated severe storms, accompanied by strong winds and large amounts of small hail over the central and eastern interior, however the South African Weather Service (SAWS) will issue detailed radar-based warnings in this regard, should the need arise.

Heavier snowfall of 10 to 20cm can be expected over the north-eastern high ground of the Eastern Cape, the Drakensberg region of KwaZulu-Natal and the Lesotho mountains from Friday evening into Saturday morning.

Thunderstorms, combined with strong, gusty surface winds are expected over the central interior by Friday afternoon, spreading to Gauteng, Mpumalanga and KwaZulu-Natal in the evening and parts of Limpopo by Saturday.

Warnings in this regard will be issued if necessary.

Due to the pre-existing condition of water-saturated soils in parts of KwaZulu-Natal, rainfall amounts exceeding 20mm are likely to lead to localised flooding. It is therefore important for communities to take the necessary precautions to prepare for such conditions.

Bitterly cold conditions are expected to move in over the western and southern parts of the country during Thursday, spreading to the central and eastern parts by Friday and Saturday.

Maximum temperatures are not expected to exceed 14°C over the interior of the country, with maximum temperatures barely able to reach 8°C over the high-lying areas of the Eastern Cape, the south-western high ground of KwaZulu-Natal and the south-eastern and extreme southern Free State during Friday and Saturday.

Small stock farmers should be advised of these conditions and take the necessary precautions.

Rainy conditions are expected to continue over the eastern parts of Limpopo and Mpumalanga and the northern parts of KwaZulu-Natal during Sunday.

However, the public can look forward to a general clearing of weather conditions as well as a recovery in daytime temperatures from Monday onwards as the system exits the country.

The South African Weather Service will continue to monitor any further developments relating to this weather system and will issue subsequent updates as required. Furthermore, the public is urged and encouraged to regularly follow weather forecasts on television and radio.
